The UK Equality Act defines a person disabled if they have a physical or mental impairment, and the impairment has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities.
I believe all of those things you listed were much worse in the 70s (with the potential exception of microplastics) when disability rates were much lower. There is no proof that microplastics are causing autism and ADHD (and a thousand other disabilities). What has changed is diagnostic criteria. In the UK they have become much looser.
Who are the current young people's parents? Do you think any adverse effects are biologically inherited?
There is no evidence that lead poisoning, for example, can be inherited. There is some research that certain epigenetic changes can be inherited. The context is sometimes war and famine. But that is 2-4 degrees of abstraction away from your question, and we are many decades away from any kind of causative conclusion to that.
If I were to steelman your position, I think there are simpler changes to point to as potential causes here. Social media. Screen time. Time spent outside and exercising. Obesity. Time spent socialising. The new "permissive" method of parenting and teaching.
